Text Anonymizer & PII Redactor
Scrub sensitive emails, phone numbers, credit cards, and SSNs from text instantly with 100% browser-based privacy.
Protecting Privacy When Working with Large Language Models
Feeding raw enterprise documents, customer support chats, or HR notes into cloud-based generative AI systems introduces compliance risks under GDPR, HIPAA, and CCPA. Sanitizing Personally Identifiable Information (PII) before transmission ensures you can leverage AI productivity without risking data leaks.

Frequently Asked Questions
Is my confidential data saved on your servers?
Never. This tool operates 100% in your browser using local JavaScript regular expressions. Nothing is saved, logged, or communicated over the internet.
Can this tool redact credit card numbers?
Yes! It detects standard 16-digit payment card sequences (separated by hyphens, spaces, or raw digits) and scrubs them immediately.
Which AI models should I sanitize prompts for?
Any public AI service (such as ChatGPT, Anthropic Claude, or Google Gemini) where organizational terms of service or privacy regulations prevent sharing unredacted Personally Identifiable Information.
What redaction format is best for LLMs?
The bracketed token format (e.g. [EMAIL_REDACTED] or [PHONE_REDACTED]) is ideal for LLMs because the model still understands the semantic role of the entity without knowing the private value.
